No, not if you are using a released ghc tarball because they include the output of happy and alex. You only need happy and alex if you want to build the development version of ghc from darcs. > Among Happy versions, it is visible only a couple latest ones, and to install > any of them, one needs Cabal. > Installing Cabal is as follows: > make install > mkdir -p dist/tmp > ghc --make -cpp -Wall -DCABAL_VERSION=1,2,3,0 -i. -odir dist/tmp > -hidir dist/tmp Setup.lhs -o setup > make: ghc: command not found. > > We have a `make' loop: ghc --> Happy --> Cabal --> ghc Remember that you always need an existing ghc binary to be able to build ghc from source. > Old Happy was good: it did not require GHC -- as I recall. Do I mistake? Happy is written in Haskell and typically people build it from source using GHC. > Now I have to install GHC from binary, and it will report of library version > mismatch ... > and so on. > Do not you think that, generally, something is going wrong here? You'll need at least a ghc binary to bootstrap with.
